More about stacked and clustered columns

Use stacked columns when you have multiple data series and you want to emphasize the total. For example, if you want to plot all the different kind of show tickets (day, evening, full price, discounted, member, nonmember) by zip code.

Use clustered columns to compare data across both categories and data series. For example if you have entries like strongly agree, agree, neutral, disagree, and strongly disagree, by customer segment.
